Hey Sudha ji , I'v a few ideas on the placement , a bed takes 9'x6'3'' so place it on the 15' Wall(you can reduce the width by removing side drawers,then you get 3' extra for bigger wardrobes on both sides) with one wardrobe on each side one for him and one for yourself and a chest of Drawers to keep other stuff handy and two Ottomans or love seat in front of the bed so you have enough space in front of the bed for traffic as well,and on the front wall to the bed place your Wall hung T.V,
PLEASE keep the colours light , use white marsh by Asian Paints or Honey dew , here are some pics .

Thanks Vikrant ji, this is a super quick useful reply :-) liked pic 2 more but then will need storage like in pic 1, May not go for storage above the bed/head board. Thanks again.
